In what may be the simplest tech story MM&FF has ever done, we'll show you how easy it is to dress up one of the most overlooked yet most important areas beneath the hood of your Mustang.

Pro-5.0 Shifters, makers of the now legendary Power Tower shifter, has branched off into other Mustang components over the last couple of years, including shifter knobs, ring-and-pinion sets, and more recently, lower control arms. With a CNC milling center at the ready, Pro-5.0 has been revisiting its Mustang heritage to come up with new products for the ponycar enthusiast, one of which is its new billet tensioner pulley.

It's a shame that you can put all of your time and money into an engine bay only to have the single most important item staring you right in the face with its shoddy, stamped-steel body.

The serpentine belt tensioner has long been overlooked, as the stock unit does its job quite well. However, as these models get older and older, the bearing can fail, thus causing your serpentine belt to go flying.

Whether you want to take your Mustang that extra mile for the show arena, or you simply want something of better quality, the Pro-5.0 billet belt tensioner pulley has you covered on both accounts, as its billet 304 stainless steel construction and sealed bearing makes it a trick piece. The pulley retails for $89, and we wouldn't be surprised if it outlasted your next two or three engines.

Installation takes about five minutes, and while it's mostly a remove and replace procedure, we thought we'd shoot some photos to show the novice how to do it and everyone how good it looks.
